6. Finally, turn the lens slowly clockwise until the status indicator flashes green (not red or
amber).
7. To exit the Focus Assistant, press the Control button again.
Note:
The Focus Assistant is switched off automatically after 15 minutes.
8. Retighten the focus puller.
9. Open the Live View page in the web browser and check the quality of the image.
Notes:
• The view in front of the camera should not be changed during focus adjustment (steps 5 and 6). If the
camera is moved, or if a finger or other object is placed in front of the lens, steps 3 - 7 will have to be
repeated.
• If movements in front of the camera cannot be avoided, the Focus Assistant should not be used.
• If the Control button is not released within two seconds, AXIS Dynamic DNS Service is enabled instead
of the Focus Assistant.
• If the camera is mounted so that the Control button cannot be accessed, you can still use the Focus
Assistant. Follow the instructions above but mount the camera after step 4 (pressing the Control
button) instead and skip step 7.
Adjusting the back focus (AXIS P1311)
The back focus of AXIS P1311 might need to be adjusted when attaching a new lens that has
specifications that are different from the original lens.
Turn the back focus screw clockwise to move the sensor
away from the lens by 0.5 mm/r. Do not force the screw
beyond the end stop since it can damage the camera.
